Where the huge SoftBank-Saudi tech fund is investing

It's one of the biggest tech funds in the world. And it's investing... fast.

The Softbank Vision Fund was unveiled less than a year ago, backed by Saudi Arabia and Japan's SoftBank(SFTBF). By May it had raised $93 billion, out of a planned $100 billion, to spend on technology businesses of the future.

Saudi Arabia is the biggest Vision Fund investor, followed by SoftBank. Other investors include Apple(AAPL), Qualcomm(QCOM), Foxconn, Sharp(SHCAY) and Mubadala, the sovereign wealth fund of the United Arab Emirates.

The Vision Fund expects to raise the final $7 billion in the next month or so but it's wasting no time in putting the committed cash to work. It's already invested in10 firms, leading funding rounds worth at least $7.7 billion.

Here's what it has backed so far this year:
